Will people ever become extinct in a long time from know?

Question

Like only animals still alive on earth. I just was thinking about it. Back up your answer too please. Thanks!

Answer 1

Of course, the planet earth is slowly warming up to extreme conditions eventually the radiation levels will be dangerously high. The earth will be all water. The sun is a star so like any star there is a shelf life and once the sun burns out the earth will freeze thus another ice age of course we are talking millions of years

Answer 2

Global Warming isn't going to wipe out mankind. In 1000 years, even if the worst effects of climate change takes effect and all the polar ice in the world melts, sea level would rise by 10-20 feet. This would sink perhaps a hundred miles of coast land. Most of the land away from the coasts would be habitable.

The human species will be around for another couple millions of years if we don't wipe ourselves off or are destroyed by natural disasters. After that, we would've probably evolved into something that no longer resembles humanity's current form, and would not be considered human.

*If our descendants continue to remain on earth without colonizing other planets, they will die when the earth's core cools and the earth loses its magnetic field, which shields us from cosmic radiation. This "might" within 1-3 billion years.

*Another scenario is when the sun becomes a red giant, engulfing or almost engulfing the earth and cooking the planet's crust into molten lava. This will happen within 4-6 billion years.

*Finally, we might be hit by country-sized asteroid, wiping out most of the life on earth. Or a super volcano like Yellowstone erupts, again, wiping out much of the live on earth.
